New Yorker on Steven Cohen

The New Yorker has a long account of the federal pursuit of money manager Steven Cohen that includes these details about the FBI's treatment of Mr. Cohen's former colleague, Mathew Martoma:

When Martoma regained consciousness, Agent Kang told him that the F.B.I. knew about "the trade in 2008." Both Rosemary and Mathew immediately understood what he meant. The other agent, Matt Callahan, hung back, but Kang was aggressive. "Your whole life is going to be turned upside down," he said. "You're going to lose all your friends, and your children are going to grow up hating you, because you're going to live your years in a jail cell." According to Rosemary, Kang said that the government would "crush" Martoma unless he coöperated. "We want Steve Cohen," Kang said....

Despite warnings from Agent Kang that if Martoma went to trial the F.B.I. would "ruin his life," Martoma's attorneys never broached the notion of a plea deal. Here was a hedge funder who might finally deliver Cohen and, because of his enormous profits from the bapi trade, would face extensive jail time if he didn't. Yet Martoma was intransigent. Eventually, a team of F.B.I. agents returned to Boca Raton and, in front of the children, marched him out of his house in handcuffs.
